Worksheet Section 2-8 Proving Angle RelationshipsObjectives: Understand the Angle Addition Postulate and use it to find unknown Angle measures Understand Supplements and Compliments and use to find unknown Angle measures Use algebra to find unknown Angle measure Use Angle relation theorems to prove Relationships with 2 column proofsAngle Addition PostulateR is in the interior of PQS if and only if m PQR + m RQS = m : Find the measure of Angle 1 if the measure of Angle 2 is 56 degrees and Practice:If and , find the measure of Angle 3.
Perpendicular lines) Perpendicular lines intersect to form four right angles. Theorem (Definition of right angles) All right angles are congruent. Theorem (Definition of Perpendicular lines) Perpendicular lines form congruent adjacent angles. Example: Write a two-column proof. Given: ∠ ABC and ∠CBD are complementary.
